This turns ravenscar_arch_ops into an abstract base class and updates
all the places where it is used. This is an improvement because it
avoids any possibility of forgetting to set one of the function
pointers. It also makes clear that these functions aren't intended to
be changed dynamically.
This version of the patch removes the prepare_to_store method, as it
is unused, and it is easy enough to add if it is ever needed.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.
This patch adds support for debugging Ravenscar tasks, similar to what
is done for ppc and sparc.
gdb/ChangeLog:
* aarch64-ravenscar-thread.h, aarch64-ravenscar-thread.c:
New files.
* aarch64-tdep.c: #include "aarch64-ravenscar-thread.h".
(aarch64_gdbarch_init): Add call to register_aarch64_ravenscar_ops.
* Makefile.in (ALL_64_TARGET_OBS): Add aarch64-ravenscar-thread.o.
(HFILES_NO_SRCDIR): Add aarch64-ravenscar-thread.h.
(ALLDEPFILES): Add aarch64-ravenscar-thread.c.
* configure.tgt (cpu_obs) [aarch64*-*-*]: Add ravenscar-thread.o
and aarch64-ravenscar-thread.o.
* NEWS: Add entry documenting Ravenscar tasking support
on AArch64 ELF.
